Abstract
A test structure for testing electrical properties of a material comprises a first loop and a second loop, which are connected to form a closed test loop. A signal generator, for generating a test signal, is coupled to the first loop and the second loop. A signal propagation switching logic is coupled to the first loop and to the second loop for alternatingly flipping the test signal between the first and second loops, such that the test signal moves uninterrupted through the closed test loop. A probe logic detects any degradation of the test signal as the test signal travels along the closed test loop.
